Leonard wants to know how fast he can throw a ball, so he hangs a 2.3 kg target on a rope from a tree. He picks up a 0.5 kg ball of clay and throws it horizontally against the target. The clay sticks to the target and the clay and the target swing up to a height of 1.5m above the initial position. How fast did Leonard throw the ball of clay?
KE+PE = KE+PE
The Attempt at a Solution
I drew it out and thought this equation might work, but i don't think it's right for many reasons.
unrealistically high velocity.
There's no way for me to check this answer, so can someone tell me if this is right?
